Abstract 247: Effect of Post Resuscitation Care Frequency on Outcome After Cardiac Arrest
Determination of the impact of the treatment frequency, hospital size and capability on mortality of patients admitted after cardiac arrest for post resuscitation care to different intensive care units in Austria.
Methods: Prospectively recorded data from 242,588 adults consecutively admitted to 87 Austrian intensive care units over a period of 13 years (1998-2010) were analyzed retrospectively.
Results: In total 5,857 patients had suffered cardiac arrest and were admitted to an intensive care unit for post resuscitation care. Observed hospital mortality was 15% in the non cardiac arrest cohort (36,460 non survivors) and 56% in the cardiac arrest cohort (3302 non survivors; p<0.0001). Patients treated in intensive care units with a high frequency of post resuscitation care generally had higher severity of illness. Intensive care units with a higher frequency of post resuscitation care showed improved risk adjusted mortality. The SAPS II adjusted, observed to expected mortality ratios (O/E-Ratios) in the three strata (less than <18; 18 to 26; more than 26 resuscitations per ICU per year) were 0.869 (95-%-confidence interval: 0.844 - 894), 0.876 (0.850 - 0.902) and 0.808 (0.784 - 0.833).
Conclusions: Intensive care units, providing post resuscitation care at a high frequency, were associated with improved outcome. Establishing cardiac arrest care centers might be a reasonable step to improve outcome after cardiac arrest.
